Codes

[Antique]

I used a mini reader with "Motorist" to do a diagnosis and it came back with 5 error codes, unfortunately when I clicked on them I got the message that they were having difficulty finding the page. Did search but could only find the answer to one.

Codes:

P1860. TCC PWM Solenoid circuit electrical/transmission transfer case contact plate D short circuit to Battery.

B1270. Servo motor potentiometer defrost circuit short to Battery.

C1511. Left front wheel pressure reduction performance problem.

P0200. Injector malfunction.

C1184. ABS system is not operational.

The ABS light comes on intermittent and can go off for days, weeks or even months. So what do I do now. I have read so many different solutions to some of the problems but could the fact there appears to be so many "short to the battery" be the main problem. Changing sensors, but which one/s.

I have posted this on my old post so I hope you don't mind my posting it as new.

Could be a bad earth?

Bad earth where, at the Battery?

I am a bit concerned about going to a mechanic and saying look I have these codes can you sort it out; without knowing exactly what the problem is. They could still bamboozle me with tech talk. I suppose I have to trust someone.

The thing is I keep seeing reports about the sensors costing £120 each. But when I do a search they come up at around £25/30 each.

Anyway thanks have to think about and see if I get any more suggestions.

Check terminals to the Battery are greased and tight.

They shouldn't be too dirty or green, also bearing in mind the chap who's positive Battery cable had a break in it recently (Rx400 owner couldn't start his car after returning to airport car park recently)...

Not saying it's the same problem as yours but is worth checking the simple things first - should be able to feel the negative cable from the Battery to the ground point on the chassis for any breaks/abnormalities.

Running a temporary additional ground/earth cable from negative terminal on Battery to car chassis could be another simple task to see if this is where the fault lies...

It is really unlikely you have a whole bunch of sensors that need replacing.

If you think back, did you have any major work done to the car (timing belt/spark plug change) a few weeks or months before the problem first occurred?

Ta,

Chris.

To be honest no, this problem with the ABS light came about some two years ago but every time I went to have it checked out the light was not on and the check showed no errors. Most recent service 3 Months ago (full) asked them to check it out, again no errors. Good thinking batman on the negative Battery lead. The fact so many of the error suggest a short to Battery makes me suspicious that it could well be something like you suggest. I will give it a look at the weekend. I will also give the sensors a good hose down as someone suggested on an earlier post.

Thanks
